I would like to ask the author, the optical flow diagram is cropped into 1,2,3,4 and merged into one, but what are the 6, 7, and 8 in Figure 2 that you provided? Are they the right eye, left and right lips of the entire optical flow diagram?
The5, 6, 7, and 8 in Figure 2 are that we cropped from original optical flow images by using facial landmarks. Block 5 is divided into 1,2,3,4 blocks which are used to extract fine-grained features of face.
